HTML Template Errors?

This error is either because there is no id assigned to the div ex.

Shannan is correct. Post the code here and we can probably help correct.

My designer figured it out. Thanks everyone. HTML is a nightmare! *mental note to free up lead gen budget for Marketo HTML support :)

Always happy to help ;)

Hi guys, i've got the same issue - trying to import templates used in "lesser" systems and created by external designers from days long gone, and while I've cleaned a lot of the HTML code up - this error has got me completely stumped!

I can do really basic HTML but the answers you guys have posted have also got me stumped.
I wouldn't even know what line of code to paste here to show someone.

What should I be looking for in the HTML, and what should it look like when it's correct?

Below is a sample HTML of a region I would to be editable;

<tbody>
<tr>
<td style="padding-top: 9px;padding-left: 18px;padding-bottom: 9px;padding-right: 18px;mso-table-lspace: 0pt;mso-table-rspace: 0pt;-ms-text-size-adjust: 100%;-webkit-text-size-adjust: 100%;">
                        
                            
<table border="0" cellpadding="18" cellspacing="0" class="mcnTextContentContainer" width="100%" style="border: 1px solid #999999;background-color: #EBEBEB;border-collapse: collapse;mso-table-lspace: 0pt;mso-table-rspace: 0pt;-ms-text-size-adjust: 100%;-webkit-text-size-adjust: 100%;">
<tbody>
<tr>
<td valign="top" class="mcnTextContent" style="mso-table-lspace: 0pt;mso-table-rspace: 0pt;-ms-text-size-adjust: 100%;-webkit-text-size-adjust: 100%;color: #606060;font-family: Helvetica;font-size: 15px;line-height: 150%;text-align: left;">

Hello, After looking at your code here are a few items.
You need to have IDs set for the sections you want editable and you also will need to include the class that allows for editability (class="mktEditable")
Inside each <td> you should insert a div set (example using a portion of your provided code below underlined). Each editable section in your code must have a different ID and also include the editiable class.

<td valign="top" class="mcnTextContent" style="mso-table-lspace: 0pt;mso-table-rspace: 0pt;-ms-text-size-adjust: 100%;-webkit-text-size-adjust: 100%;color: #606060;font-family: Helvetica;font-size: 15px;line-height: 150%;text-align: left;">
<div class="mktEditable" id="mainContent">

You also have a lot of extraneous Microsoft Word-generated code that you'll need to clean up as well.
